Instead of coming up with a catfish, Riley captured the biggest goldfish she's ever seen.

"I don't know, it's beautiful!" Riley shouted as she smiled and showed her massive catch to a friend's camera.

"I was really amazed," Riley told KMBC 's Marcus Moore. "It was a beautiful fish, something to see up close." Riley told Moore that she thought she had caught a traffic cone, not a fish, at first.

"I've got skills and everything, but that day, it was a pure accident. A pure accident," Riley, who learned to fish as a child in Mississippi, said.

As to how the fish got in Troost Lake, Riley said there are several possibilities.

"There's a lot of theories. One that he went down the old toilet bowl and ended up in the right place," Riley laughed. "And the one of someone not able to take care of a baby goldfish and threw him in, and he survived."

The YouTube video that showed Riley making the catch has been a big hit at her office. "Every two seconds you hear "Oh, no!'" Riley said.

Instead of keeping the fish, Riley decided to throw it back so it could continue to live in Troost Lake.

"It's a pretty high bar for the rest of the fish," Riley said. "I don't think I'm going to top it anytime soon. It's still out there, but maybe the next time I catch and bring him in, maybe it'll be his time to be done."

Riley said the fish wasn't injured when she threw him back in the water.
